9 4.0 Installation instructions 4.1 Installation WARNING! The appliance may be installed by authorised personnel only! The unit and the exhaust duct system must be in principle installed so that it is accessible for maintenance work, can be easily installed and dismantled and removed from the vehicle wit hout great effort. Installation and connection of the appliance must comply with the latest technical regulations, as follows: The electrical installation must comply with national and local regulations. The gas installation must comply with national and local regulations Side installation If the appliance is installed on the same side of the vehicle as the entrance door, it is desirable that the door does not cover the refrigerator's vents. (Fig. 5, Clearance door/ventilation grille at least 25 mm). Otherwise ventilation could be impaired which causes a loss in cooling perfor mance. Awnings are often placed at the door side of a caravan. This complicates evacuation of combustion gases and heat through the ventila tion grilles (loss in cooling performance)! (Fig. 5) The air vent grilles are blocked. There must be a distance between the door and the air vents of at least 25 mm! If the door/grille distance is between 25 mm and 45 mm, we recommend installing a Dometic ventilation kit (item no /0) to achieve an optimal cooling performance in high ambient temperatures. European Standards EN 1949 European Standards EN , EN , EN , EN The appliance must be installed in such a way that it is shielded from excessive heat radiation. Excessive heat impairs performance and raises the energy consumption of the refrigerator! Fig. 3 (Fig. 6 )The air vent grilles offer an unobstructed dissipation of heat and exhaust gas even when the door is opened. Deviations from these installation instructions without prior notification of Dometic result in Dometic GmbH's warranty obligations becoming void! Air vent grille not blocked! OK! Fig. 4 9

10 4.1.2 Rear installation Rear installation often causes an unfavourable installation arrangement, as ideal ventilation cannot always be assured (e.g. the lower ventilation grille is covered by the bumper or the rear lights of the vehicle!). The maximum cooling performance of the aggregate is actually not available. CAUTION! The maximum cooling performance is not available! Do not apply this installation method, as it does not provide proper ven tilation! Please refer to the description in section 4.2. Air vent grille not blocked! OK! Fig. 5 Another unfavourable method of rear installation is to install the air intake and exhaust grilles (Fig. 9) at the side wall of the recreation vehicle. The air-heat recirculation is very restricted which means that heat exchangers (condenser, absorber) cannot be adequately cooled. The optional method of an additional air vent grille installed in the floor also exhibits an insufficient air flow duct Draught-proof installation Refrigerators in motorhomes, caravans or other vehicles must be installed in a draught-proof manner (EN 1949). This means that the combustion air for the burner is not taken from the living space and that exhaust fumes are prevented from entering the living space. Adequate sealing between the back of the refrigerator and the vehicle interior has to be provided. Dometic strongly recommend using a flexible sealing for this purpose, in order to facilitate future removal or installation of the appliance during maintenance. WARNING! By no means use durable sealing compounds, fitting foam or similar material to realise draught-proof installation of the refrigerator! Do NOT use any easily inflammable materials for sealing (in particular silicon sealing compound or similar). Risk of fire! The device manufacturer's product liability and warranty shall lapse if such materials are used. Dometic Refrigerators of RM8xxx Series feature a groove running all around outside and bottom side to facilitate the insertion of such flexible lipped seals (see next figures). Fig. 6 10

11 Dometic recommend mounting a strip with a heat deflector plate into the installation recess above the appliance (Fig. 8). This allows the ascending hot air to escape directly outside. This deflection plate must also be provided with a lipped seal. That ensures that the refrigerator can easily be removed for maintenance or repair. Deviations require the consent of the manufacturer! 4.2 Ventilation and air extraction of the refrigerator A correct installation of the refrigerator is essen tial for its correct operation, as due to physical reasons heat builds up at the back of the appli ance which must be allowed to escape into the open air. Fig. 7 Fig. 8 Fig. 9 Fig. 10 The flexible sealing is pressed into the groove running around the housing. Press the side provided with the sealing knob firmly into the groove. Take care that the sealings uniformly abut the housing. The cavity in-between the outer vehicle wall and refrigerator is completely isolated from the vehicle interior. Intrusion of exhaust fumes into the living space is prevented. Fumes will escape through the upper ventilation grille to the outside. The draught-proof installation does not require a special exhaust gas duct to be used. In the event of high ambient temperatures, full performance of the cooling unit can only be achieved by means of adequate ventilation and extraction. Ventilation is provided for the unit by means of two apertures in the caravan wall. Fresh air enters at the bottom, extracts the heat and exits through the upper vent grille (chimney effect). The upper ventilation grille should be positioned as high as possible above the condenser (A). Install the lower ventilation grille at floor level of the vehicle, allowing unburnt gas (heavier than air) to escape directly into the open air. Should this arrangement prove impossible, a ventilation aperture must be introduced by the manufacturer of the vehicle into the recess floor in order to avoid the accumulation of unburnt gas on the floor (Fig. 11,12). 11

The flue gas is vented directly through the upper grille. Do not use any kind of aluminium flue pipe to lead the flue gas out. The T-piece (Fig. 26) must be trented towards the outer wall. Fig Insert frame and screw into position. Fig Insert ventilation grille. Fig Lock ventilation grille. Fig. 23 CAUTION! An installation other than described will reduce the cooling capacity and jeopardise the manufacturer's warranty/product liability. 5 Insert winter cover. Fig. 24 Fig

15 4.5 Installation recess The refrigerator must be installed draught-proof in a recess (also refer to Section "4.1.3"). The measurements of the recess are stated in the table below. Push the appliance far enough into the recess until the front edge of the refrigerator casing is aligned with the front of the recess. Allow a gap of mm between the back wall of the recess and the refrigeration unit. The floor of the recess must be level, allowing the appliance to be pushed easily into its correct position. The floor must be substantial enough to bear the weight of the appliance. Ensure that the refrigerator is installed level in the recess. 4.6 Securing the refrigerator In the sidewalls of the refrigerator, there are four plastic sleeves for securing the refrigerator. The sidewalls or strips attached for securing the refrigerator must be prepared to hold the screws firmly in place even when under increased load (while the vehicle is moving). Fastening screws and caps are supplied with the refrigerator Recess dimensions Models RMD 8501 RMD 8505 RMD 8551 RMD 8555 Height H Width B DepthT 1249 mm 529 mm 599 mm Fig. 27 CAUTION!

The refrigerator must be equipped with a shut off valve allowing to cut the supply line. Such a shut off device must be rea dily accessible to the user. * Qualified personnel are accredited experts who are able, by virtue of their training and knowledge, to vouch for the correct implementation of the leakage test. Observe the regulations stated in section 4.1. This refrigerator is provided for installati on within liquid gas equipment in compli ance with EN1949 and must be run exclu sively on liquid gas (propane, butane) (no natural gas, town gas). A fixed, pre set pressure regulator com plying with EN must be connected to the liquid gas cylinder. The pressure regulator must concur with the operating pressure specified on the rating plate of the appliance. The opera ting pressure corresponds to the standard pressure of the country of specification (EN 1949, EN 732). Only one connection pressure is permis sible for any one vehicle! A plate showing the permanent, clearly legible notice must be displayed in full view at the point where the gas cylinder is installed. The gas connection to the appliance must be installed securely and free of stress using pipe connectors and must be secu rely connected to the vehicle (a hose con nection is not permissible) (EN 1949). The gas connection to the appliance is effected by means of (Ermeto ) olive type fitting L8, DIN 2353 ST, complying with EN After professional installation, a leakage test as well as a flame test have to be car ried out by qualified personnel* in confor mity with EN A test certificate has to 10 Nm max CAUTION! 20 Nm max SW 14 SW 17 Fig.34 Dometic refrigerators of this series are prepared for a connection pressure of 30 mbar. For connection to a 50 mbar gas system, use Truma VDR 50/30 equipment admission pressure controller. 17

18 4.9 Electrical installation WARNING! The electrical installation shall be carried out by qualified personnel* only. * Qualified personnel are accredited experts who are able, by virtue of their training and knowledge, to vouch for the correct implementation of the leakage test. The electrical installation must be in accordance with the national regulations of the respective countries. The connection cables must be routed in a way to prevent contact with hot compo nents of the unit/burner or with sharp edges. Changes to the internal electrical installa tion or the connection of other electrical components (e.g. external fan) to the internal wiring of the appliance will render the e1/ CE admittance as well as any claims from warranty and product liability void! Mains connection The power should be supplied by a pro perly grounded socket outlet or a groun ded non detachable connection. Where a socket outlet with mains supply is used, the outlet must be freely accessible. Should the connection cable be damaged, have it replaced by Dometic Customer Services or by qualified personnel to avoid hazards. We recommend leading the power supply via a board-side fuse protection Battery connection The machine's 12V connection cable is connected (observing correct polarity) to a terminal strip. The wiring for the heating element (refer to A, B wiring diagram connections; connection cable white/red) must be direct and by the shortest possible route to the battery or electric generator. Cable cross sections and cable lengths Motorcaravan & Caravan (inside) 4 mm ² (RML = 6 mm ² ) < 6 m 6 mm ² (RML = 10 mm ² ) > 6 m Caravan (outside) min 2,5 mm ² CAUTION! (EN1648-1) 2,5mm² Fig. 35 If the appliance is installed in a caravan the respective leads for the 12V+ and 12V- connections A/B and C/D must not be connected to each other on the caravan-side (EN ). Provide a 16 A fuse to protect on-board 12 V circuit. In order to ensure that the 12V power supply is shut off when stopping the engine (otherwise the battery would discharge within a few hours), perform the power supply to the heating element (cf. page 30, connection A/B in wiring diagram) in a way to have the 12V supply only live while the vehicle ignition is switched on. The connection C/D (interior light, electronics, cable black / violet) must be permanently provided by a 12V DC power supply to be protected by a 2A fuse. 18
